There has not been a whole lot of innovation in the area of unstructured data within the mainstream BI toolsets recently. While I agree that unstructured data is becoming increasingly important, the question is at what pace and at what relative effort to good old so-called structured data? Informix's Data Blades of a few years ago was much ballyhooed but never went anywhere in the market.
I don't see it being a big priority for 2-3 more years, especially as we continue to have needs of the vendors in the area of structured data. And I see it coming from the major players.
